Concrete thinking is a cognitive style that focuses on tangible, literal concepts and facts. Individuals who think concretely often struggle with abstract ideas or hypothetical situations. They prefer clear, straightforward information and rely on direct experiences to understand the world around them. This type of thinking is common in children and can also be seen in some adults, particularly those with certain cognitive conditions. For example, individuals with autism spectrum disorder may exhibit concrete thinking, making it challenging for them to grasp idioms or metaphors. Overall, concrete thinking emphasizes the importance of observable and measurable elements in understanding reality.
